IMPROVEMENT 1N HAYPRESSES.

Specification forming part of Letters Patent No. lf), dati-d July l2,1864'.

same in the line a: w, Fig. l. Fig. 3 is 'a' de` tached view of thecapstan by which the beater is pperated, and which will be hereinaftermore particularly referred to.

Similar letters of reference indicate corresponding parts inthe severalfigures.

The object of my invention is to produce a press in which are combinedthe advantages of both the vertical and horizontal press now in use.

An objeetionablefeature in the use of the vertical press is that itsgreat height renders it necessary for the press to be placed withinasupportin g building or structure having what is known as a pit orbasement story,7 in order to obviate the labor of elevating to thelling-door the substance to be compressed.

In horizontal presses as hitherto constructed it has been impossible toemploy beaters for packingthe hay or other substance previously` to itsbeing acted upon by the follower or main compressing medium.

My invention consists, chiefly, in a press which occupies an inclinedposition,and which is provided with oblique guidways, which are of suchforni and arranged in such manner that a beater may be effectivelyemployed in order to perform the packing operation,whch has to be donewith the feet in the horizontal presses heretofore devised.

In order that others skilled in the art tol which my inventionappertains may be enabled to fully understand and use the same, I willproceed to describe its construction and operation.

In the accompanying drawings, A may represent the box of the press,which is sustained in the inclined position represented in Fig. 2 bystandards B B. f

B B represent grooves or guideways formed partially in the standards B Band partially in the vertical and oblique timbers C C C G, saidguideways being of circular or curved form, constituting gentle slopesfor a short distance in the immediate vicinity of the box A, and then,as they extend from or leave the latter, rapidly approaching a verticalposition.

D is a beater which is moved up within the ways B B by means of acapstan, E, through the medium of a cord, E', which permits the beaterto descend by gravity with great force against the substance within thebox A, after it (the beater) has been elevatedto the uppermost part ofthe grooves B B.

F is a door where the hay is placed loosely ,within box A, between thebeater D and a follower, G, the manner of operating which will bepresently explained. i

FF are side pieces erected at the respective ends of the door F, andemployed in connection with the latter when opened to prevent the wasteof hay or other substance being com pressed.

H H represent doors hinged respectively to the upper andunder side ofthe box A. These doors may be opened so as to permit bands to be appliedto the bale within the box A, after which the bale may be passed out atthe door H.

d may represent spaces formed in the respective proximate ends of thebeater D and follower G, for the purpose of facilitating the iapplication of the bands to the balles. The capstan E is mountedhorizontally upon a shaft, c, which has its bearings in bars or timbersI I', and a sweep, E2, attached tov the said shaft, provides means forthe turning of the capstan in customary manner. resented as occupying` aposition above the timber I', but in practice this arrangement may bereversed, so that the horses attached to the sweep will pass under thetimber I. The capstan E in its transverse section has the shape of anegg or of an ellipse, and is secured eccentrically upon the shaft e, sothat when it is turning to wind upon it the cord E', for the purpose ofelevating the beater D, its point of action upon said cord E willdecrease in distance with relation to the shaft c commensurately as thebeater D rises within the inclined ways B B. The cord E is fastened tothe end of the beater D in any suitable manner and passes over pulleys JJ', and its attachment to The sweep Ez is rep the capstan E is madethrough the mediumA of a block, e', which is fitted loosely within acontinuous groove, c2, which is formed upon the periphery of the capstanE. Y

e3 is a pivoted bar fitting within a corresponding slot in the capstanE, and affording a firm bearing for the block e while the capstan isbeing turned to elevate the beater D.

The parts are to be so arranged that when the capstan has made almost acomplete revolution upon `its axisv the beater will be elevated to theproper height within the groove, from which it may be permitted todescend against the hay or other substance within the box A.

e5 is a spring which acts to throw the bar e3 into the groove c2, s0 asto cause the block c to move round with the capstan E until said blockcomes in contact with a timber or bar, I2, which causes the block c tomove inward, or in the direction of the axis of the capstan E, entirelyout of contact with the block e',

Whose bearing is thus removed, the block be-v ing then allowed to slidearound in the groove c2. When the bar e3 strikes against the timber l2,the beater D will have been elevated to the height from which it isallowed to descend. A

It is manifest that the peculiar form of the capstan E adapts it to actwith increasing force upon the cord E as the beater ascends in the waysB B, inasmuch as the point of action of the capstan E approaches itsaxis or fulcrum as fast as the wheel is turned. The advantage of thusconstructing the capstan is that its elevating capacity increases inproportion as the beater approaches a vertical position, when, ofcourse, it will require greater power to elevate it than when in an,approximately horizontal position.

J2 J2 may represent toggle-joint levers attached by suitable pivots tothe follower G.

undergone the requisite packing process, the

beater may, by any snitabledevice, be retained in contact with saidsubstance to hold it against the pressure of the follower G.

The levers J2 J 2 may be drawn together by means of a rope or cord,whichextends from the capstan E and passes around friction-wheels j j,inserted intothe ends of the levers J2 J2.

The position of the levers J2 J2 may be reversed by a weight, K,attached to the ends of a cord, 7c, which passes over a pulley, 7c',under a pulley, k2, and is attached to the ends of one of the levers J2or J 3, the pulleys 7c 7a2 being mounted between standards K K.

Having thus described my invention, the

following is what I claim as new and desire to secure by Letters Patent:

l. The combination of the beater D, working in inclined Ways B B, withthe box A in an inclined or horizontal position, substantially asdescribed and represented.

i 2. An eccentric, elliptical, or other irregularly-formed drum orroller, E, employed, in connection with beater D and ways B B, to applyan increasing power to elevate the beater D, as explained.
